From Purpose and Scope: "The Gillette 1º x 2º Quadrangle, Wyoming, and South Dakota was evaluated to find volumes of rock considered favorable for uranium deposits and which could contain at least at 100 mt tons U3O8 with an average grade of 0.01 percent U3O8 or more. All geologic environments to a depth of 1,500 m (5,000 ft) evaluated through the use of surface investigations and subsurface information."

Abstract: This report lists the machine-readable data files developed for the Madison Limestone and Northern Great Plains Regional Aquifer System Analysis (RASA) projects that are stored on magnetic tape and available from the U.S. Geological Survey. Record format, file content, and size are given for: (1) Drill-stem-test data for Paleozoic and Mesozoic formations; (2) geologic data from the Madison Limestone project; (3) data sets used in the regional simulation model; (4) hydraulic-head data for the Lower and Upper Cretaceous aquifers; and (5) geologic data for Mesozoic formations of the Northern Great Plains.

From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

From Introduction: "The Hot Springs Quadrangle covers an area of approximately 18,500 km2 and is in southwestern South Dakota and northwestern Nebraska between latitudes 43º to 44ºN. and longitudes 102º to 104ºW. (Fig. 1). The quadrangle was evaluated at the surface and in the subsurface to a depth of 1500 m to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

From Introduction: "The Lemmon Quadrangle, South Dakota and North Dakota, was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

From purpose and approach of study: The purpose of this study was to develop a predictive model of the ground-water system for use as a management tool. The model will be used by State and local officials in evaluating the effects of alternative methods of controlling or developing the ground-water resources of the Big Sioux aquifer in Minnehaha County.
